Abstract
The utility model discloses a clamping valve for an upper associated machine. The clamping valve is used for conveying white carbon black and stopping conveying in the natural rubber production process. The top end of a left brake arm and the top end of a right brake arm are connected to the two sides of the top of a supporting frame respectively. A left clamping roller is fixed to the bottom end of the left brake arm. Two right clamping rollers are fixed to the bottom end of the right brake arm. A transmission rod is driven to stretch or contract by an air cylinder arranged in the middle of the left side and the right side of the supporting frame. The left brake arm and the right brake arm are pushed to rotate anticlockwise and clockwise respectively by the transmission rod. When the transmission rod stretches out, a conveying rubber ring is squeezed by the left clamping roller and the right clamping roller at the same time, and finally the left clamping roller and the two right clamping rollers make linear contact at the same time while being set apart through the conveying rubber ring to close and stop the conveying rubber ring; when the transmission rod contracts, the conveying rubber ring is in an unblocked state and normal conveying can be carried out.
Description
Technical field
The utility model belongs to a kind of clamping valve when controlling the conveying of natural rubber production process white carbon and isolating agent, is specifically related to clamping valve for a kind of upper subsidiary engine.
Background technique
White carbon is that precipitated silica, aerosil, superfine silicon dioxide gel and aerogel mix; for fine powder shape; white carbon has superpower adhesive force, tear-proof and heat-resistant aging quality, and after rubber grain mixing, banburying can obtain high-quality rubber product.When natural rubber being pulverized with banburying, the combined amount of white carbon is controlled and had strict proportion requirement, in traditional processing technology process, use metallic material to carry and switch control, because of white carbon, this is difficult to accomplish accurately control and close down in time as fine powder.
For addressing the above problem, the utility model is for a kind of upper subsidiary engine clamping valve of carrying baihuixiong accurately to transmit and closing down in time.

A kind of upper subsidiary engine comprises with clamping valve: outer support frame, be rotationally connected plate, cylinder, drive link, dunnage, left brake arm, right brake arm, left clamping roller, right clamping roller, conveying rubber ring, pressing plate, support annulus and adpting flange, described outer support frame profile is that square body is each side provided with and is rotationally connected plate, described being rotationally connected is fixed with cylinder on plate, described outer support frame top is each side provided with two relative dunnages, two dunnages that are arranged on left side connect left brake arm top, described left brake arm tail end is installed a left clamping roller, two dunnages that are arranged on right side connect right brake arm top, described right brake arm tail end arranges two right clamping rollers, being arranged on supporting frame left hand cylinder is connected with left brake arm by drive link, being arranged on supporting frame right cylinder is connected with right brake arm by drive link, in the middle of the dunnage of four, described outer support frame top, be provided with the bad shape pressing plate of circumference, described conveying rubber ring upper end is fixed on supporting frame top by pressing plate, described conveying rubber ring bottom is provided with support annulus.
The utility model further improves and is: described drive link stretches by the adjustment of cylinder air pressure, and when described drive link stretches out, left brake arm and right brake arm be take respectively dunnage and as the center of circle, turned counterclockwise and clockwise rotate.
The utility model further improves and is: described left clamping roller side diameter is 1.5 times of right clamping roller, guarantees that left clamping roller can contact to clamp the realization of conveying rubber ring with right clamping roller simultaneously simultaneously and close down.
The utility model further improves and is: described drive link is when retracting completely, described left clamping roller and right clamping roller and conveying rubber ring are contactless, now conveying rubber ring is normally conveying of unimpeded state, when described drive link stretches out completely, left clamping roller and two right clamping rollers push conveying rubber ring simultaneously and form line and contact, and in the time of a bit, conveying rubber ring is closed condition by the extruding of a left clamping roller and two right clamping rollers.
The utility model further improves and is: described outer support frame consists of square sheet material, and top is covered with steel plate, and described outer support frame top is provided with circular material feeding mouth, locates to be provided with pressing plate.
The utility model further improves and is: described conveying rubber ring connects miscellaneous equipment by adpting flange.
Accompanying drawing explanation
Fig. 1 is side view of the present utility model.
Fig. 2 is plan view of the present utility model.
Wherein: 1-outer support frame, 2-is rotationally connected plate, 3-cylinder, 4-drive link, 5-dunnage, the left brake arm of 6-, the right brake arm of 7-, the left clamping roller of 8-, the right clamping roller of 9-, 10-conveying rubber ring, 11-pressing plate, 12-supports annulus, 13-adpting flange.
Embodiment
Describe embodiment of the present utility model below in detail:
Clamping valve for a kind of upper subsidiary engine, as shown in Figure 1, by square sheet material, form outer support frame 1, top is covered with steel plate, supporting frame 1 top is provided with circular material feeding mouth, pressing plate 11 is fixed on supporting frame 1 top by conveying rubber ring 10 tops, and conveying rubber ring 10 bottoms are fixed into circle and are connected with miscellaneous equipment by adpting flange 13 with supporting circumferential ring 12.
Supporting frame 1 both sides, top are respectively provided with two dunnages 5 mutually, two, left side dunnage 5 connects left brake arm 6 tops, left brake arm 6 bottoms are fixed with left clamping roller 8, two, right side dunnage 5 connects right brake arm 7 tops, right brake arm 7 bottoms are fixed with two right clamping rollers 9, the side diameter of left clamping roller 8 is 1.5 times of right clamping roller 9 side diameters, supporting frame 1 left and right sides intermediate portion is respectively provided with and is rotationally connected plate 2, the cylinder 3 that the left and right sides arranges is fixed on supporting frame 1 by being rotationally connected plate 2, and be connected with right brake arm 7 with left brake arm 6 respectively by drive link 4, drive link 4 stretches by cylinder 3 air pressure adjustment, when drive link 4 stretches out, left brake arm 6 and right brake arm 7 be take respectively dunnage 5 and as the center of circle, are turned counterclockwise and clockwise rotate, when drive link 4 is retracted completely, left clamping roller 8 and right clamping roller 9 are contactless with conveying rubber ring 10, now conveying rubber ring 10 is in the normal conveying of unimpeded state, when drive link 4 stretches out completely, left clamping roller 8 and two right clamping rollers 9 push conveying rubber ring 10 simultaneously, until forming line with two right clamping rollers 9 across conveying rubber ring 10 simultaneously, left clamping roller 8 contacts, now conveying rubber ring 10 is the state of closing down, cannot carry out conveying, because the double-deck line contact squeeze that the elasticity of rubber itself and three niproll cylinders form can avoid fine powder shape white carbon to continue lower leakage completely.
